Master Disconnect Question- Honda Specific

[tom91ita]

fwiw, here are pictures of the affected section of the wiring diagram for my 1st gen crx and where i connected everything to for the typical shut-off switch.

the notations are rather cryptic but i think you should be able to get the gist.

the resistor was just wired to the cage where the kill switch was attached.

Back to the beginning...

I have totally disconnected the alternator and the engine still takes about 3 seconds to shut off.

When I kill either the ignition swith or master disconnect, the ignition shuts off, fuel pump shuts off and the tach drops instantly to zero.

However the engine continues until it runs down.

Any ideas?????

Thanks,

Is there an idle cut-off selenoid on the carburetor? Ususally this is the reason for run-on. As for the master switch. I use a relay, used in alarms and emobilizers, that has a grounding terminal. When power is cut the relay gounds out the ECU power wire. Oh, and I've got a spare relay in my tool box JIC,

No high-tech stuff at all...
Carb is a Weber DGV and a stock electronic ignition.

Even a type 1 (Beetle) VW's solex has an idle cut-off selonoid. That said and realizing that a DGV doesn't have an idle cut-off selonoid, I'd think that your ignition still has some residuel power in it after shut-off. If you have the same four pole switch as I have, mine's from Longacre, there's no grounding in the switch. The switch just disconects the two battery terminals from the two that go on into the motor. You need a way to ground out the ignition wire from the key when you cut the power. That's why I use the relay. Cut the power to the relay grounds out the ignition key wire and the alternator, same thing with turning off the key switch as I have the BCS and key switch wired in series, it takes both the master switch and the key toggle switch on to start. Turn either off and the car goes off instantly. The current has to have a place to go and it sounds like it can only go throuch the ignition system now.

Thanks James,

How exactly do you ground or dump that residual power?

I need to add the master kill switch on my carbed CRX. I have the six post switch and get that the large lugs go between the pos battery terminal and the starter and power distribution block.

I believe I then need to run the N.O. contacts on the switch in series with the positive ignition coil post to kill ignition when the switch is turned off. Does the ignition switch (stock) just remove power from the coil or does it ground the coil?

Also for the alternator, do I just add a wire from the alternator output post (on the alternator) to the resistor through the master disconnect switch?

Thanks
